[1 point, 10 tries] A 2.98 kg steel ball strikes a massive wall at 11.4 m/s at an angle of α =63.1° with the plane of the wall. It bounces off with the same speed and angle (as seen in the figure below). If the ball is in contact with the wall for 0.246 s, what is the average force exerted on the ball by the wall? Answer: 2.46e+02 N 2 . [1 point, 10 tries] A 49.5 kg girl is standing on a 163 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.48 m/s relative to the plank. What is her velocity relative to the ice surface? Answer: 1.14e+00 m/s 3 . [1 point, 10 tries] An 8.07 kg mass moving east at 13.0 m/s on a frictionless horizontal surface collides with a 11.6 kg mass that is initially at rest. After the collision, the 8.07 kg mass moves south at 2.70 m/s. What is the magnitude of the velocity of the 11.6 kg mass after the collision? Answer: 9.24e+00 m/s Go to problem [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] 1-19 Status: Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y
